Day/night Tests officially sanctioned by ICC

Participating countries may agree to play day/night Test matches. The home and visiting boards will decide on the hours of play which will be six hours of scheduled play per day while the two boards will also decide on the precise brand, type and colour of ball to be used for the match.

Following any mode of dismissal that is not permitted off a no-ball and which is not the subject of an Umpire or Player Review, the third umpire shall, subject to the availability of suitable technology, immediately check the fairness of the delivery (foot-fault only). If the delivery was not a fair delivery, the third umpire shall advise the on-field umpire by two-way radio who should recall the dismissed batsman, indicate that the batsman is not out and signal no-ball.

Big change to ODI field restrictions - only four fielders allowed outside the circle in non-powerplay overs. During the powerplays only three fielders are allowed out. On the other hand, the bowling powerplay is gone - only the 10-over and batting powerplays.

Apparently the Super Over's official acronym is the OOPSE. No idea if this is new, but I did lol.

Clause 3.3 (ii) of Appendix 2, which deals with LBW protocols, has been amended and the margin of uncertainty applicable to the point of impact with the pad has been increased so that it is the same as provided for determining the projected point of impact with the stumps i.e. if the centre of the ball is shown to be impacting in line within an area demarcated by a line drawn down the middle of the outer stumps (and the bottom of the bails), then the decision will always be out.

If the whole of the ball is shown to be impacting outside the line of the stumps, then the decision will always be not out. If there is anything in between, the original on-field decision will stand.

As such, this clause will now read as follows: "If a 'not out' decision is being reviewed, in order to report that the point of impact is between wicket and wicket (i.e. in line with the stumps), the evidence provided by technology should show that the centre of the ball at the moment of interception is in line within an area demarcated by a line drawn below the lower edge of the bails and down the middle of the outer stumps.

"If an 'out' decision is being reviewed, in order to report that the point of impact is not between wicket and wicket (i.e. outside the line of the stumps), the evidence provided by technology should show that no part of the ball at the moment of interception is between wicket and wicket."

every single ODI rule change that doesn't change stupid over restrictions deepens the wound
